Hi David,
I started with the "modelglueapplicationtemplate" skeleton that comes
with Model-Glue. The call to the Security Controller is triggered like
this:
The default event of the application has an event-type "needsLogin"
<event-handler name="page.index" type="needsLogin">
<broadcasts />
<results>
<result do="template.main" />
</results>
<views>
<include name="body" template="pages/index.cfm" />
</views>
</event-handler>
This event-type is defined as
<event-type name="needsLogin">
<before>
<broadcasts>
<message name="getLoginStatus" />
<message name="checkPermission" />
</broadcasts>
<results>
<result name="notLoggedIn" do="notLoggedIn"
redirect="true" />
<result name="noPermission" do="noPermission"
redirect="true" />
</results>
<views />
</before>
</event-type>
So we're broadcasting "getLoginStatus" and "checkPermission" before
any event of type "needsLogin" and doing a redirection if certain
reults are set in our event. The Security controller listens to both
of the two messages
<controller id="Security" type="myApp.controller.Security">
<message-listener message="getLoginStatus" />
<message-listener message="checkPermission" />
</controller>
That's how the getLoginStatus() method of the Security Controlles gets
triggered.
I said "getting some errors lately" because we never ran into this
issue during development but now (as we're beginning to use the
application) it appears more often. I can't remember of some certain
change that started the problem.
I will definitely look into bean injection on the weekend - maybe we
can get around the problem, if we use a SesionService.cfc as you
suggested instead of a Helper.
Cheers,
Steve
